LOCK MECHANISM.

Application filed January 24, 1925.

To all whom it may concern:

Be it known that I, IIENRY N. SLEDGE, a citizen of the United States, and a resident of Jersey City county of Hudson, and State of New Jersey, United States of America, have invented certain new and useful Improvements in Lock Mechanisms, of which the following is a specification.

This invention relates to looks.

At the present time when holdups are prevalent, bandits will enter a store and compel the clerk or cahsier to operate the combination of a safe lock and open the safe. In such holdups, speed is essential since the bandits obviously want to make a quick getaway. i

This invention has for its salient object to provide a lock so constructed and arranged that a considerable period of time must elapse after the combination of a lock has been worked before the lock bolts can be withdrawn. and the safe door or other door can be opened.

Another object of the invention is to provide a look so constructed and arranged that the manual operation of a combination lock or equivalent mechanism will set in operation slow moving power driven means for withdrawing a locking bar or detent thereby permitting the release of the locking bolt after a period of time has elapsed.

Another object of the invention is to provide lock mechanism combining a manually operable device with slow moving power driven means for controlling and withdrawing a locking bar or detent.

Another object of the invention is to provide lock mechanism combining a manually operable device and power driven mechanism within the control of the operator but set in operatlon by the manually operated device, said power driven means complet ng .the release of the locking bolt.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which- Fig. 1 is an elevational view of a mechanism constructed in accordance with the in vention.

Fig. 2 is an elevational view broken away showingthe detentfivithdrawn thereby permitting the operation of the locking bolts.

Fig. 3 is sin-enlarged sectional elevation talen subs anti y nline 3-3 of g-v 1, an y a the spindle and disk.

Serial No. 4,436.

Fig. 1 is an enlarged sectional elevation taken substantially on line 44l of Fig. 1.

The invention briefly described consists of a door locking mechanism which may be of any desired character and includes a detent for retaining the locking bolts against release until the operator has worked the combination or otherwise manipulated the lock to release the detent. In this invention, the detent comprises two sections, one of which is withdrawn by the usual combination lock mechanism. The other section of the detent is adapted to be moved by a power driven means and the withdrawal of the manually controlled section of the detent operates to connect the other section to the power driven means. Any suitable form of power driven means may be used but it is important that this means withdraw the detent section slowly and gradually so that aconsiderable period of time must elapse before the tent section is withdrawn and releases the locking bolts. Optional means is also provided whereby the manually operated device can be used to release both sections of the tentent from the locking bolt. Further detailsojt the invention will appear from the following description.

In the particular form of the invention illustrated, the door locking means comprises a disk 10 mounted on a spindle- 11 and having pivotally connected thereto, on 0pposite sides of the spindle, locking bolts 19. and 13. It will be understood that the spindle 11 extendsthrough the door and has a suitable handle secured thereto for rotating The disk 10 has an arm 15 extending outwardly from its periphery.

The lock control mechanism comprises a detent having a pair of sections A and B.

These sections are slidably mounted between rollers 16 and17, and stops 18 and 19 are provided for limiting the movement of the sections. The section B as shown in Fig. 1

is positioned in the path of the arm 15 and prevents the rotation of the disk 10 unless this section is Withdrawn, to the position shown in Fig. 2. y a

The section A of the detent mechanism has pivotally connected thereto an arm 20 having an offset end 21 formed-thereon. The end 21 of the arm 20 is adapted' to enter .lperipheral notehes 22 in a series of tumblers 23 (one of which is shown) when the proper combination has been worked and the notches in the various tumblers are disposed in alinement with each other. lVhen the end 521 of the arm drops into the notches, the tumbler disks canybe rotated tothe position shown in dotted lines in Fig. 1, thereby moving the section A of the detent to the left against the stop 18.

The detent section B has mounted therein a spindle 30. A lever 31 is secured to one end oi the spindle andone end 32 of the lever normally rests on the upper edge 33 of the detent section A. Section A has one end of its upper edge cut away as shown at 34 and when the section A is \i 'ithdraivn to the left, the end 32 ot the lever 31 will drop into the recess 34: and rest on the surface 35 at the bottom oi the recess. The lever 31 is extended on the opposite s de of the shaft 30 from the end 32 and is tnrther extended upwardly to form an arm 36. An 21111167 is secured to the opposite end of the spindle 30 and is disposed parallel with the arm 36. Thesetwo arms are connected by a cross pin or cross rod A power driven toothed wheel or gear is mounted above the detent sections A and B and the teeth of this wheel are so positioned relative to the cross pin 38 that the cross pin will be positioned between the teeth when the lever moves in an anti-clockwise direction and this movement takes place as the detent section A is withdrawn from the left. g

It is contemplated that the power driven wheel 4C0 will be rotated continuously and at a slow rate of speed. After the detent A has been withdrawn and the lever swings in an anticlockwise direction, the engagement of the cross pin 38 between the teeth oi the wheel 40 will cause the detent section B to he gradually withdrawn by power derived from the wheel 40 until it reaches th'eposition shown in 2 when the lever 31 will he swung in a clockwise direction causing the cross pin to be released from engagement by the teeth of the wheel. When the detent sections have been withdrawn from the position shown in Fig. 1 to the position shown in Fig. 2, the arm 15 of the disk 10 is rel used and the disk can be rotated thereby w lidraiying the locking bolts 12 and 13 from their locking posit-ion. p

In order to prevent friction between the arm 15 and the dtentsection B a roller 4-1 is preferably iiiounted at the upper edge of the seams B in position to engage the outer endot the arm 15. v

It my be desirable at times to provide f 'or the release of the detent sections A, B by the operationof the combination locltwithoutwaiting for the power driven wheel 4:1) to release the detent B. For this reason a latch (see land-2) isypivotedgat. 51 the sec en A andis' adapted togbe, swun L n clockw se directsonto the posit-ion shown continue the withdrawal of the detent B. It should be unt erstood that the latch 50 can be op erated only from the inside of the door, thus making it impossible for the person endeavoring to open the door to couple the detent sections from outside the door.

Although one specific einl'iodiment of the invention has been part'cularl v shown and described. it will he understood that the invention is capable of modification and that chan in the construction and in the arrai ament ot the various cooperating parts may be made without departii'ig from t 'it or scope of the invention, as exin the allowing claims. that claim is 2 l. riot-l: mechanism comprising locking elements a detent for preventing the operation of said elements, power driven means for withdrawing said detent and manually operable means for setting said means in operation.
